New ACTv2 Ethanol & Diesel Water Sensor 

The new ACTv2 Ethanol & Diesel Water Sensor can be used for testing the intrusion of water in any vessel containing ethanol blended fuels.  

The ACTv2 Ethanol & Diesel Water Sensor is the only water sensor on the market which tests for the intrusion of water in vessels containing ethanol blended fuels.

Why use the ACTv2 Ethanol & Diesel Water Sensor?

  • The "ACTv2 Ethanol & Diesel Water Sensor" is the only water sensor that has been certified for use with ethanol fuels in addition to most other fuel types. 
  • It is easy to use and is a totally portable battery operated system.
  • Since ethanol will absorb water, there is no way of knowing that your water sensor is detecting water entering the tank before the ethanol absorbs the ingress of water from outside the tank. Since there is no way to know that the water sensor you are using has detected the water before it was absorbed, this makes an acoustical test of an underground tank not valid.
  • Most water sensors require that water be added to the tank as part of the test. When you add water to an ethanol fuel you run the risk of causing a phase separation of the fuel. Phase separation is where the ethanol and gasoline will separate making the fuel unusable.  


How does the Vaccum Test Procedure work?

The "ACTv2 Ethanol & Diesel Water Sensor" method consists of placing a conductive probe into a vessel-containing all types of motor fuels including diesel and gasoline blends E10 and E15 products. The conductive probe is connected to an indicator box that clearly displays when the probe comes in contact with water and tests if there is an intrusion of water into the vessel under vacuum.

The "ACTv2 Ethanol & Diesel Water Sensor" can be used independently, as part of the Mesa2D tank testing system or any other tank testing system on the market.

Don’t leave your company at risk of being accused of causing a phase separation because you added water to the fuel!

There are times when an ethanol fuel tank has been tested using a water sensor and a few days later the fuel phase separates. The possible causes are as follows:

  • Your water sensor test did not detect the intrusion of water causing a phase separation.
  • It rained after your visit and water entered the tank because of a loose cap or fitting, etc. causing a phase separation.
  • There was a fuel delivery after your test and because of water unknowingly included in that fuel delivery caused a phase separation due to either water in the residual fuel or water at the base of the tank. The addition of the fuel delivery caused the problem but the tank tester could easily be blamed if they had added water to the tank in order to conduct a water intrusion test.
